Seattle Seahawks fans triggered the earthquake seismometer at the nearby University of Washington with the loudness of their cheers as Jimmy Graham scored a game-winning touchdown during Sunday’s game against the Houston Texans.

Pacific Northwest Seismic Network, which records earthquakes in Washington and Oregon, says that it’s not just the simple audible sound of cheering that sets off the meter, but “crowd generated vibrations” based on stomping and riotous cheering. They shared a video of the spike on their YouTube channel.

The network has previously studied the earthquake impact of Seahawks fans. The crowd at the CenturyLink Field stadium reached 136.6 decibels in 2013 and 137.6 decibels in 2014, earning the crowd two Guinness World Records for loudest roar at a sports stadium. The Seahawks were, however, beaten out by the Kansas City Chiefs for the record in 2014, hitting 142.2 decibels at Arrowhead Stadium.

These numbers measure approximately between a magnitude 1 and 2 earthquake, but the Seismic Network says it’s hard to measure because the size of the crowd across the stadium and the length of time of cheering dilute the ability to create a Richter reading.

The first time the Seahawks set off earthquake meters is affectionately called the “Beast Quake” of Jan. 8, 2011, when Marshawn Lynch’s touchdown secured the team’s victory.

A month before the earth-quaking game, the Seahawks Twitter account boasted of their loudness on National Poetry day, saying “Sunday Night Football. Seatown is where it goes down. There’s no place LOUDER.”
